These will brace the upper and lower section of the notoriously weak Falcon chassis. It installs with no modification at all but we recommend longer screws to ensure proper grip and help prevent stripping of the standard self-tapping screws. Please see the video below prior to purchase. We do not recommend using an MSC with this as the servo will need to be spaced up for fitment. When using the standard Falcon MSC mount, one screw hole is not used. If using the Stadium Blitzer MSC mount, both holes are used.
